1. A method, comprising: sending, by network equipment comprising a processor, a request to a user equipment requesting return of a report, the request comprising a first resource setting and a first report setting that indicates to the user equipment to include channel measurement information in the report generated by the user equipment, and the request further comprising a second resource setting and a second report setting that indicates to the user equipment to include interference information in the report generated by the user equipment based on a beam sweep operation performed by the user equipment and to include channel state information reference signal resource indicator signal-to-interference-plus-noise ratio data in the report; receiving, by the network equipment from the user equipment, the report generated by the user equipment; and communicating, by the network equipment, with the user equipment via a transmit beam that is selected based on the report.
This invention relates to wireless communication systems, specifically improving beam selection and interference management in millimeter-wave (mmWave) or other high-frequency networks. The problem addressed is the need for accurate channel and interference measurements to optimize beamforming and resource allocation in dynamic wireless environments. The method involves network equipment sending a request to user equipment (UE) for a report containing both channel measurement information and interference data. The request includes two resource settings and two report settings. The first resource and report settings instruct the UE to measure and include channel conditions in the report. The second resource and report settings direct the UE to perform a beam sweep operation and include interference information, specifically signal-to-interference-plus-noise ratio (SINR) data derived from channel state information reference signal (CSI-RS) resources. The UE generates the report based on these settings and returns it to the network equipment.
